Engine valve spring for stock applications

Melling VS-580 is a standard replacement engine valve spring built for stock and performance-oriented applications across a wide range of classic Chevrolet, GMC, Buick, Oldsmobile, Cadillac, and Pontiac engines. It uses corrosion-resistant steel and a dual-spring design to match the pressure and height requirements listed for the application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Detailed description

The Melling VS-580 valve spring is specified as a standard replacement spring with dual-spring construction and corrosion-resistant steel. It is listed with an installed height of 1.61 in. (41.0 mm), coil bind height of 1.13 in. (29.0 mm), spring open height of 1.16 in. (29.0 mm), installed pressure of 80.0, and open pressure of 200.0. The VS-580 is used in stock exhaust and non-position-specific applications across many Chevrolet, GMC, Buick, Oldsmobile, Cadillac, and Pontiac engines, including Chevrolet Camaro, Corvette, Nova, Impala, and C10 applications where listed.

Melling’s Stock line covers standard, mid-range, heavy-duty, and race-ready valve spring needs with multiple wire sizes, materials, and spring pressures. The VS-580 fits within that range as a standard replacement option for engine builds that need a direct spring specification match. Use the VS-580 when the application calls for the listed spring dimensions and pressure values, including Chevrolet Camaro and Chevrolet Corvette fitments shown in the catalog data.

What it is used for

• Replacing a worn or weakened valve spring.
• Restoring valve control in stock engine assemblies.
• Matching specified spring height and pressure requirements.
• Supporting exhaust-valve applications where listed.
• Addressing spring fatigue, loss of tension, or inconsistent valve action.

Installation notes and tips

Verify the listed installed height, coil bind height, and pressure values before installation. Several fitments note camshaft restrictions, including applications marked “Not For Use With MTC-1 Camshaft” or “Use With CCS-2 Camshaft,” so confirm the camshaft requirement for the exact engine build. Fitment includes 1967-1986 Chevrolet Camaro, Corvette, Nova, Impala, and C10 applications, along with additional Buick, GMC, Oldsmobile, Cadillac, and Pontiac models as listed.
